D70 enables experienced-to-amateur photographers to easily adopt digital technology into their existing camera system. The camera has 3D Digital Matrix Image Control, Digital Vari-Programs, and a lens servo system. Nikon engineers chose the MPC17511 H-bridge motor driver IC from Freescale Semiconductor to power the motor. The monolithic driver integrates control circuitry for driving integrated and external n-channel MOSFETs. Designed for PWM control frequencies up to 200 kHz, the analog IC offers increased battery life for the portable application.

A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
